This might be a trivial question, but I searched for it, and could not find a solution. I am using Cesium 1.22. In the HelloWorld example, the globe just does not show up. I can see the stars and even the sun, but not the earth. I even tried this on Cesium 1.21, but the globe does not render there too. I have had Cesium up and running multiple times earlier with no problems, but this came out of nowhere. I suspect I have messed up my nodejs packages.
If someone has had such a problem earlier and had found a fix for it, please share it with me. I would be grateful.
